This stack looks like mangled C++ names from the Sun C++ compiler (or
some other C++ compiler), in particular of iostreams. There is a
chance that some symbol of the GNU C++ library and the Sun C++ library
are in conflict, e.g. 'cout' or the like. If that is the case, the Sun
initializers might find themselves initialize g++ objects - which
would certainly break.

Of course, it could be just as well anything else.

No, in C++, these are keywords, not #defines.
